Actually, BOO. I understand how you feel, but I wouldn't expect a child on a child's scooter to have to wear headgear. If Mini BOO had been running around the playground at full speed she could well have tripped and ended up with the same injuries.
I just think back to my youth when I was continuously playing on a scooter on the pavements, no knee pads, head gear, etc.
I think it's different for bikes and skate boards, but scooters are not that dangerous.
Be careful not to wrap her in cotton wool. She is your baby and I understand fully your need to protect her, but she will have accidents in the course of growing up. She will be more cautious in future.
I speak as a mum who, looking back on it, made my son when he was small, more cautious than he should have been. Fortunately, he released the apron strings himself when he realised what I was like!!
Please don't stop her going on the scooters if other kids are doing it. It won't do her any favours.
I really hope her teeth will be OK. She'll be fine.
Were you so cautious with Big BOO?
Much Love
